HENRY LITTLETON, OF MARICOPA, CALIFORNIA.

BURNER.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed November 2, 1911. Serial No. 658,183.

To all whom it may concern:

Ile it known that I, HENRY InT'rLEToN, a citizen of the United States, residing at Maricopa, in the county of Kern, State of Californiav7 have invented certain new and useful Improvements in Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled .in the art to which it appertains to make and use the same. p

This invention relates to that class of oil burners described in my (fo-pending application -for Letters latenti tiled Aug. 17, 1911, under Serial Number` 644,517.

An objection to this type of burner in which a single jet of steam is relied upon to 'atomize the oil, is that the jet usually atomizes only the lightest portions of the hydrocarbons and forces the heavier portions butslightly 1n advance ofthe nozzle, and as a result these heavier portions drip down.

through the grate bars and are not fully utilized. To obviate this disadvantage, I provide in the present invention an auxiliary steam, supply which serves to raise the telupci;1t1|ie of the cooled partially atomized fuel so thatsubstantially complete atomization takes place before entrance of the fuel to the furnace.

lV ith the above object in View the invention consists of the certain novel details of construction and combination of parts llere-4 elevation of a burner embodyingr my inlprovements. Flg. 21s a longitudinal sectional view through the burner. Fig. t is a cross lsectionalfw'iew taken on the line 5l-fil Fig. 2.,

Referring now to the drawing in which like characters of reference designate similar parts, l() designates. the oil supply T con# pling,one ofthe alined lnfainh'es of which is closed by a reducer ll, the'sarne being internally threaded for the reci-pilon of the threaded end ol' a steam jet pipe 12 which extends axially through the alined branches of the coupling and projects beyond both One end of the jet pipeis equipped with an elbow connection 13 which 'may bc connected in any preferred manner to a steam supply'. The lateral branch 10 of the coupling is connected in any suitable manner to an oil supply. -An outlet elbow-10 is connected to the couplingr for 'drawing off thecontents thereof when desired.

A reducer 14 is threaded into the other of said alined branches and a T-coupling 15 is threaded on to this reducer, the reducer being furthermore provided with a threaded axial nipple 1G for the reception of the threaded end of an oil pipe 17 which houses the steam jet pipe 12 and extends axially through the alined branches of the T-conpling 15. Theoil pipe extends slightly beyond the discharge end of the steam jet pipe so thatthe oil is mixed with steam before its escape from t-he oil pipe. During such mixing it. is evident that the temperature of the fuel will be lowered so that complete atomization does not talreplace. Toraise the temperature of this`atomized fuel I connect the lateral branchofthe coul pling 15 with suitable steam supply, suitable pipe connections as will be presently. dei

. Threaded into the T-coupling 15 is a nipple 18 which houses the oil ipe, and is furthermore equipped with a plpe extension 19, the reducer connection 19 between both.

of these parts being disposed -atthe dis- 'charge end of the oil pipe so that the eX- tension may be unscrewed to permit access vto the discharge end of the oil pipe for cleaning and repairs. The outer end of the extension is preferably equipped VWithan elbow 20 which is provided in it-s front Wall with a discharge slot 21-and is furthermore provided below the slot with a small sup- I lement1ary discharge orifice 22 as described in the above mentioned co-pending application, this elbow cooperating with the eX- tension 19 in forming a mixing chamber.

lly now referring to Fig. 2 it will be seen that the independent .supply of steam led into the T--eoupling 15, is conducted through the nipple-18A and reducer connection 19 to the discharge end of the oil pipe where' by virtue of its higher temperature than the cooled at'olnized fuel, it merges with and raises the temperature of the fuel so that. substantially complete atomization takes place before escape of the fuel through the discharge openings into the furnace.

In order that the jet pipe 12 may be held centered Within the oil pipe 17, a plurality of screws or the like 23 are inserted vthe lateral branch adapted for connection to an oil supply, longitudinally bored plugs closing the alined branches'of said coupling and one of said plugs having an exteriorly threaded nipple projecting beyond said coupling, a steam jet pipe in said coupling threaded into the bore of one plug and exloending through the bore of the other plug, an oil conducting pipe threaded into the .bore of the last named plug surrounding said jet pipe and extending beyond the discharge end thereof, a -second T-coupling having one of the alined branches threaded on to said nipple and having the lateral branch adapted for connection to a steam supply, a pipe threaded into the other alined branch 'of said coupling `surrounding said oil supply pipe `and terminating short of the discharge end thereof, a reducer threaded on to the discharge end of the last named pipe, and a pipe threaded into said reducer and alining with said oil supply` lin testimony whereof, I. affix my signature, in presence of two Witnesses.
